Beyerdynamic DT 770 Pro or Custom One Pro?

I am currently using a sennheiser PC 350 headset, and have recently acquired a new mic, and now I'm looking for new headphones. I have narrowed my search down to these two sets of headphones: Custom One Pro's and DT 770 Pro -32 ohms edition. Which one would be best. Factors are listed from highest priority to lowest priority.

Comfort

In terms of comfort, I am open to small mods like velour pads for the COPs. Also, I prefer to have little (to no) clamp, as well as good isolation. It also needs to be able to be driven by a mobile device, and not too brittle, as it will be travelling. Thank you for your help!

I would "guess" the 16-Ohm Beyer COPS would be easier for mobile audio devices.

The DT770 32-Ohms are consider to be best when driven by a decent headphone amplifier.

Thank you for your response. I am already leaning towards the COPs, and was just wondering which would be best in the long run, because the dt 770 are like 160 dollars, while COPs w/ velour are like 230+.
